Let's say you wake up with flat, boring hair and don't have 45 minutes to spend bonding with your curling iron. You know, just hypothetically. That would be the perfect moment to road-test this quickie hair trick I spotted on Rosie Huntington-Whiteley as she hustled through Heathrow Airport yesterday.

At first glimpse, Rosie appears to have bouncy heat-styled hair, but upon second glimpse, only one front section on each side of her head has been curled. The hat adds to the illusion that the curls we see in the front continue all the way around her head. Note to self: This really is such an easy way to look cute for air travel too (because who's going to bother doing a full styling job only to flatten her hair under a neck pillow for a few hours?).

What do you think of Rosie Huntington-Whiteley's quickie curling iron job? Do you ever curl just your front and/or top sections as a quickie hair cheat?
